Parametric Search and Field Search

Parametric search and field search both use values in fields to filter your result set. For both searches, you should have normal search text to create a subset of your total document set, and then use the field to filter that result set to the most relevant values.

The key difference between parametric search and normal field search is that:

When deciding whether to use parametric or field search, consider the following examples:

Example 1

A set of product descriptions all contain a COLOR field:

The COLOR field probably contains only a few values, so a parametric search probably makes the most sense in this case.

Example 2

A set of book descriptions have an AUTHOR field:

In this case, the AUTHOR field might contain hundreds of different values. Additionally, users might not know the full name of the author they want to search for. A field search is probably the most appropriate in this case.
